This application claims the benefit of U.S. Provisional PatentApplication No. 61/421,740, filed Dec. 10, 2010, the entire disclosureof which is hereby incorporated herein by reference.

FIELD OF THE INVENTION

The invention pertains to electronic equipment racks and cabinets. Moreparticularly, the invention pertains to a method and apparatus formounting rack components, such as cable trays, routers, switches, etc.,in such racks and cabinets.

BACKGROUND OF THE INVENTION

The use of an electronic component rack or cabinet for holding aplurality of electronic components, usually in a vertical stack, is wellknown. Such racks are used in many environments, such as network serverfarms, telephone switching stations, electronic equipment closets ofoffice buildings containing large amounts of networked electronicequipment, or in countless other environments in which electrical oroptical signals need to be switched between numerous electroniccomponents. In such environments, it is not uncommon for a plurality ofracks to be tightly packed side by side in a room, with each rackcontaining a number of vertically stacked electronic components, such asrouters, cable trays, data processing equipment, switching equipment,etc. Furthermore, the number of wires and cables that enter and exit thecomponents in the racks can be voluminous, leading to an environment inwhich it is very difficult to mount and dismount components to and fromthe racks.

These electronic component racks often comprise little more than a base,four vertical posts and a few horizontal rails running between the poststo hold the structure together. The posts and/or rails may include holesfor mating with holes on the components so that bolts can be placedthrough the mating holes to attach the components to the racks.

Typically, a rack component is installed on a rack by sliding it in acomponent slot of the rack from the front and then installing boltsthrough mating holes on the front panel of the component (or on flangesextending laterally from the front panel of the component) and on thefront posts of the rack. More specifically, a component can be slid intoa slot in the rack until the front panel (or front flanges) butt upagainst the front posts of the rack. The holes on the panel or flangesalign with corresponding holes on the racks and the panels or flangesare bolted to the rack through the mating holes, thereby affixing thecomponent to the rack. In some cases, the components are installedessentially similarly, but are slid in from the rear of the rack towardthe front, rather than from the front toward the rear.

However, the components that are mounted in these racks often aresufficiently heavy that they require support toward the rear of the rackas well as the front of the rack. Hence, the components must be bolted(or otherwise attached) to the rack both at their front and at theirrear (or at least somewhere else along their lateral sides). Frequently,however, the racks are arranged in such a manner that it is difficult,if not impossible, to gain access to both the front and the rear of therack and/or sides of the rack. For instance, it is not uncommon for theplurality of racks to be positioned side by side in a long row such thatonly the front (or only the rear) of the rack is accessible to aninstaller.

This situation makes it very difficult to access the rear (or front) ofthe rack in order to bolt a rack component to the rack near the front aswell as the rear of the rack.

SUMMARY OF THE INVENTION

The invention pertains to a system for mounting components to a rackcomprising brackets that can be mounted to the rear of the rack throughthe opening in the front of rack before the component is inserted into aslot and mating sleeves running along the sides of the components. Thebrackets include arms that extend forwardly towards the front of theslot. After the brackets are attached, the component can be slid intothe slot from the front with the sleeves sliding over and engaging thebrackets. In this manner, the component can be slid into a slot on therack with the brackets sliding into the sleeves, thereby providingsupport for the component along a substantial portion of the depth ofthe component without the need to bolt or otherwise fasten the componentto the bracket after the component is in the rack. Accordingly, with thebrackets attached, a component can be installed in a rack without theneed for any access except from the front of the rack.

DETAILED DESCRIPTION OF THE INVENTION

FIG. 1 is a perspective view of an electronic equipment rack 10 foraccepting a plurality of electronic components in vertically stackedslots and showing a rack component 20 in the process of being insertedover two brackets 30 in the rack in accordance with the principles ofthe present invention. The four post rack 10 of the Figures is exemplaryand the invention is not limited to application in such racks. Theinvention may be applied to other forms of racks as well as cabinets andthe like. The exemplary component 20 is a cable tray, comprising aplurality of slots 26 defined by a plurality of separators 27. A cabletray generally does not actually contain any electronic or opticalcomponents, but merely assists in the separation and routing of cables(not shown in order not to obscure the invention) through the rack 10.However, the invention is applicable to any form of component that canbe mounted in a rack or cabinet.

Typically, such racks comprise a base 13, four posts 15 a, 15 b, 15 c,15 d rising vertically from the base, and a top 12. It may also compriseone or more horizontal rails (not shown) to provide structural supportfor the rack 10. A plurality of components, such as component 20, may beinstalled in the rack 10, such as routers, servers, cable trays,switching units, etc. Commonly, the posts 15 and/or the rails includeholes 18 for accepting bolts or other fasteners that may be used toaffix components to the rack. These holes 18 will align with holes onthe housings of the electronic components so that the components may beaffixed to the rack by nuts and bolts passing through the mating holesof the rack and the component (or other fasteners). For instance, asseen in FIG. 1, a rack component, such as cable tray 20 typically mighthave flanges 22 extending laterally from its front face 25, the flangesbearing holes 29 for aligning with the corresponding holes 18 on therack.

Usually, the components that are installed in racks are of astandardized width, w, corresponding to the width of the rack. However,the depth, d, is not necessarily standardized. That is, components ofdifferent depths can be installed in a single rack, with deepercomponents simply extending further towards the rear of the rack thanless deep components.

As previously mentioned, lighter components often only need to beattached to the rack at their front faces. However, heavier componentsrequire additional support along the sides or towards the rear of thecomponent.

Hence, many racks contain holes on side or rear rails or on the rearposts 15 c, 15 d of the rack that are designed to align withcorresponding holes on the sides, rear or other flanges on the component20 so that the component can be fastened to and thereby supported by therack at locations other than the front of the rack. However, oneobviously must be able to access the rear or sides of the rack after thecomponent has been inserted into the slot in order to attach thecomponent to the rack or otherwise support it from the rear or sides ofthe rack.

Accordingly, in order to solve this problem, the invention provides abracket and sleeve system for mounting a component 20 to a rack 10 inwhich the brackets 30 may be mounted to the rack 10 before the component20 is placed in the rack so that the installer may attach the bracketsto the rear 10 b of the rack by reaching through the front 10 a of therack 10 (or any other access point) before the component is placed inthe rack. For sake of clarity, FIG. 1 (as well as FIG. 4),shows thebrackets 30 being mounted flush against the front faces of the rearposts 15 c, 15 d in order to allow the entirety of the brackets,including the flanges 34, to be seen. However, in many, if not most,situations, it will be preferable for the installer to attach thebrackets 30 to the rear posts 15 c, 15 d with the flange flush againstthe rear faces of the posts 15 c, 15 d so that the brackets can beinstalled without the installer needing to reach around from the rearinto the rack with a screw driver to attach the brackets 30 to the posts15 c, 15 d.

With reference to FIG. 2, which is a close up view from the rear of thecomponent 20 showing the component engaged with the bracket 30(disembodied from the rack for clarity), the component 20 can be slidinto the rack 10 from the front of the rack with sleeves 22 (only one ofthe two sleeves 22 is seen in the close up view of FIG. 2) on thecomponent 20 sliding over and engaging the brackets 30, and with no needto further attach or affix the component 20 to the bracket 30.

FIG. 3 is a close up view of the exemplary bracket 30 of FIG. 1, exceptwith holes 36 deleted. The bracket 30 comprises an arm 32 that willextend horizontally along the depth, d, of the rack 10 when installed onthe rack, as shown in FIG. 1, and a flange 34 bearing holes 36 or slots38 (or any other reasonable means) for attaching the bracket 30 to therack 10. The arm 32 is sized and shaped to slide into a sleeve on thehousing of a component as will be described in more detail herein.

Referring again to FIG. 2, the component 20 is shown with no cables,separators, or electronics contained therein in order not to obscure theinvention. However, it should be understood that, typically, thecomponent 20 will be occupied with electronic circuitry, separators, orother components. Furthermore, the top and rear panels of the componentare removed in FIG. 2 also in order not to obscure the invention. Inthis particular embodiment, the sleeves 22 are located on the internalsides of the opposing lateral side panels 24 of the component (only oneside panel 24 and sleeve 22 are visible in the close up view of FIG. 2).Alternately, the sleeves can be positioned on the outer sides of thelateral side panels 24. A cable tray such as illustrated in FIG. 1normally would not have a rear panel. However, most other types of rackcomponents would have a rear panel. If the sleeves are provided on theinternal sides of the lateral side panels, then the rear panel of thatcomponent should be designed to provide spaces between its lateral edgesand the lateral side walls 24 through which the arms 32 of the brackets30 can pass in order to slide into the sleeves 22.

The sleeves 22 are sized, shaped, and positioned to slidably receive thearms 32 of the brackets 30 therein through the rear openings 22 a of thesleeves. The sleeves may be separate pieces that are attached to thecomponent or may be integrally formed from the panels of the componentitself.

FIG. 4 is a similar view to that of FIG. 1, but showing the component 20fully inserted into the rack and installed in the brackets 30. Theflanges 34 of the brackets 30 should be sized, shaped, and positionedrelative to the arms 32 so that their holes 36, slots 38, or othermounting mechanisms can be attached to the rack 10 so that, whenmounted, the arms 32 extend horizontally and parallel to each otheralong the opposing lateral sides of the rack in the depth direction, d,so that a component 20 bearing the sleeves 22 in accordance with theinvention can be slid into the front of the rack with the sleeves 22sliding over and engaging the arms 32 of the brackets 30 as shown inFIG. 4. Thus, the width between the two lateral side panels 24 of thecomponent 20 would need to be selected so that the sleeves 22 are in theproper location to engage the brackets 30 as will be described furtherbelow. Thus, for instance, if the sleeves 22 are located on the internalside of the lateral side walls 24 as illustrated in FIG. 2, the lateralside walls should be spaced a little farther apart than if the sleeveswere mounted on the external sides of the lateral side walls 24.

In one embodiment, the length of the arm 32 of the bracket issufficiently long so that it will be guaranteed to engage the sleeve ona component over at least a portion of the arm's length for componentsof different depths. The sleeves of components of lesser depth wouldsimply engage a shorter portion of the arm 32 than the sleeves ofcomponents of greater depth. Thus, components of different depths may beinstalled within the same front to back rack spacing using identicalbrackets.

In certain embodiments, the rear end 22 a of the sleeve 22 may be flaredoutwardly in order to facilitate the arm 32 of the bracket entering intothe sleeve 22 as the component 20 is being introduced into the rack.Alternately or additionally, the far end 39 of the bracket from theflange may be tapered in one or more axes. The brackets may be sized andshaped so that the installer's appendages and flesh are much less likelyto be trapped between the component, bracket, and/or sleeve via guardsurfaces. Also, a handle may be attached to or formed into the rear ofthe component to facilitate sliding it through the rack opening andthrough the depth of the rack (for rear entry environments). Forinstance, a small flange could be formed directly from the rear wall ofthe component that one could grab and pull on to help move the componentrearward, avoiding the need to place one's fingers under or beside thecomponent.

The particular embodiment of the bracket shown in FIGS. 2 through 4 isdesigned to be mounted to a rear post 15 c, 15 d of a rack. However, thebracket could take many forms depending on the particular design of therack or cabinet. For instance, FIG. 5 shows an alternate bracket 30 adesigned to be attached to a rack 10 a by bolts extending in the widthdirection, w, of the rack, rather than the depth direction, d.Specifically, this bracket 30 a comprises a first flange 34 a, likeflange 34 of the first embodiment, extending perpendicularly from therear end of the arm 32, and a second flange 37 extending perpendicularlyfrom the end of the first flange 34 a. This type of design can be usedto mount the bracket 30 a to a rack 10 a or cabinet via either siderails 16 or the rear posts 15 c, 15 d, with bolts extending laterallyrather than in the depth direction.

Other than the sleeve 22 sliding over the bracket 30 or 30 a, there isno fixation of the sleeve to the bracket and, therefore, no need toaccess the bracket after the component is in the rack. Hence, thebracket can be affixed to the rack before the component is installed;when there is access to the rear of the rack through the slot in therack into which the component will be installed. Thus, an installer canfasten the bracket to the rack by reaching inside of the rack from thefront opening into which the component is to be installed without theneed for access from the rear or sides of the rack. Then, after thebracket is installed, the component can be slid into the rack throughthat opening so that the sleeves 22 on the lateral side panels of thecomponent 20 travel over and engage the brackets. The front panel of thecomponent may then be fixed to the rack by bolts and nuts passingthrough the holes in the front panel (or front flanges) of the componentand mating holes on the front posts 15 a, 15 b of the rack as previouslydescribed. The brackets will provide support for the components alongthe entire portion of the length of the bracket arm that is within thesleeve.

Ball bearings or other bearings may be provided on the bracket armsand/or within the sleeves to facilitate smooth sliding of the bracketarms into the sleeves.

Also, one or more detent features may be provided on the bracket and/orthe sleeve to provide one or more tactile stops for the insertion of thecomponent over the brackets.

The engagement of the sleeves with the brackets not only supports thecomponent, but also provides an inherent centering feature for centeringthe components correctly in the slots of the rack.

The sleeve and/or the bracket also may be coated or entirely formed of alow friction material to ease the sliding of the bracket relative to thesleeve.

In certain embodiments, the arms of the brackets may comprise multiplepieces and may be telescoping, in the nature of a drawer support.

In certain embodiments, an automatic locking mechanism may be providedfor locking the brackets to the component. For instance, a lever, cam,wedge, jackscrew, collet, or other mechanism may be included to providea positive locking mechanism between the bracket and the sleeve (or thecomponent) to enhance the securing of the component to the rack. Suchmechanisms may entail a multiple piece mounting bracket with parts thatcan move relative to each other to effect this locking feature. Themovement needed to cause locking may be a vertical movement, such as inconventional dresser drawers, a lateral movement in the width directionof the rack, or a push-pull movement in the depth direction d of therack. Any reasonable locking mechanism that does not require manualaccess to the locking mechanism may be employed. For instance, aspring-loaded pawl mechanism or jaw mechanism may be provided inside thesleeve near its proximal end 22 b that engages a mating structure at thefar end 39 of the arm of the bracket from the flange such that, when thecomponent is slid onto the bracket in the depth direction, the pawl orjaw engages the mating feature of the end of the bracket, causing thepawl or jaw to open against the spring bias in order to pass over thefeature on the arm and then close again behind the feature to affect thelocking.

Preferably, the locking mechanism also permits the unlocking of thepawl, jaw, or other mechanism from the feature on the bracket withoutthe need to manually access the locking mechanism. For instance, incertain embodiments, the pawls, jaws or other mechanism may be designedto permit disengagement by pulling the component out in the depthdirection with sufficient force to overcome the spring bias. In otherembodiments, the mechanism may be disengaged by insertion of a toolthrough a slot in the front face of the component that can engage thelocking mechanism and be operated to cause it to unlock from thebracket. In yet other embodiments, a button or lever may be provided onor extending from the front face of the component that can be pressed orotherwise operated to manipulate the pawls, jaws or other mechanisms tocause them to release their engagement with the mating features on thebrackets.

In yet other embodiments, the locking mechanism may be a detentmechanism. For instance, a bump on the side of the bracket near the farend of the bracket from the flange may engage a divot in a narrowedportion of the sleeve near the proximal end of the sleeve.

In certain embodiments, the locking mechanism within the sleeve and thebracket may both be formed of a conductive material, such as a metal, sothat the engagement of the bracket with the locking mechanism inside thesleeve further serves the purpose of providing a tool-less groundingmethod for electrically communing the component to the rack.

In yet other embodiments, the brackets may be adjustable in multipledegrees of freedom (roll, pitch, yaw, depth, height, and/or width) sothat a single bracket can be used with different width, height and/ordepth racks and/or components and/or to permit adjustment of thebrackets relative to each other for purposes of leveling of a componentwithin in a rack. The bracket may be provided with a leveling featurethat allows adjustment of the angle of the component in the rack in oneor more degrees of freedom including roll, pitch, and yaw. The bracketand/or the component may be provided with a level indicator, such assilkscreened lines or a spirit bubble to further assist in leveling thecomponent in the rack from front to back as well as side to side.

In yet other embodiments, the bracket and/or the sleeve may be designedto assist with shock and vibration absorption. For instance, the insideof the sleeve may be lined with a resilient material 28 that absorbsshock and vibration between the bracket and the component. Alternately,leaf or coil springs may be provided within the sleeves to provide shockand vibration absorption.

FIGS. 6A through 6E illustrate four exemplary locking mechanisms forlocking the component to the bracket. In FIG. 6A, the bracket 30 b has asplit arm 32 b defining a slit 33 running longitudinally down the centerof the arm. The slit includes a carve-out portion 35. The component 20 bincludes a laterally oriented stud 27 within the sleeve 22 b that iswider in diameter than the slit 33 in the arm 32 b. When the sleeve andbracket arm are moved into engagement, the stud 27 slides into the slit33, forcing the slit to open wider to accept the stud therethrough. Whenthe stud reaches the carve-out portion 35, the slit snaps back to asmaller cross section so that the stud 27 is trapped in the carve-outportion 35. The carve-out portion 35 may be shaped with a lead taper 37so that the component 20 b can be removed from the bracket in the samemanner by which it was inserted, i.e., by pulling on the component withsufficient force to cause the stud 27 to spread the slit 33 apart wideenough to allow the stud to pass back through it and out of engagementwith the arm. FIG. 6A also illustrates leaf springs 40 inside the sleeve22 b such as mentioned in the preceding paragraph for providing shockand vibration absorption.

FIG. 6B illustrates another releasable locking mechanism. In thisembodiment, the arm 32 c of bracket 30 c also is split into two halves32 c-1 and 32 c-2 by a slit 33 a. However, in this embodiment, at leastthe front end of the arm 32 c is slightly wider than the sleeve 22 cwhen the arm is in an unstressed condition. The front ends of the twoarm halves may be tapered as shown at 41. When the arm 32 c is slid intothe sleeve 22 c, the tapers 41 meet the edges of the sleeve and forcethe arm halves to squeeze toward each other, narrowing the slit 33 abetween them. The slit 33 a is wide enough to allow the two arm halvesto squeeze together enough to permit the arm 30 c to enter the sleeve 22c. However, the friction between the arm and the sleeve will serve tolock the arm within the sleeve and allow the arm to be pulled out of thesleeve (or vice versa) only upon application of a sufficient force. Therequired force to insert and remove the arm from the sleeve should beset by proper selection of materials and slit design to be large enoughthat the component cannot fall out accidentally, but small enough sothat it can be inserted and removed without the need for force greaterthan can be applied reasonably by a single person.

FIG. 6C illustrates yet another embodiment in which the sleeve 22 d ofcomponent 20 d includes an embossed bump 51 and the bracket 30 dincludes an embossed divot 52. The bracket is positioned relative to thesleeve so that the bracket arm 32 d must bend to enter the sleeve 22 d.The end of the bracket arm may be curved so as to assure that the armwill initially enter the sleeve without being blocked by the rear edge54 of the sleeve. The bracket 30 d is resilient in the lateral directionas illustrated by arrows 53 so that the bracket will flex to enter thesleeve with the face 55 of the bracket rubbing against the inner face ofthe sleeve 22 d. Thus, when the divot 52 meets up with the bump 51, thearm 32 d will snap back slightly, thereby providing a detent-typelocking of the bump 51 within the divot 52. The bracket 32 d may bewithdrawn in the same manner, i.e., by pulling on the component 20 dwith enough force to overcome the frictional engagement of the bump 51in the divot 52.

FIG. 6D illustrates yet another embodiment quite similar to theembodiment of FIG. 6C except that, instead of an embossed bump, a springloaded ball 57 is provided in the sleeve 22 e of component 20 e to matewith the divot 52 on the arm 32 d of the bracket 32 d.

FIG. 6E shows another embodiment in which the arm 32 f of the bracket 30f includes a sawtooth pattern 61 on its top edge and one or more pins 62are disposed within the sleeve 22 f of component 20 f. The sleeve isinserted over the bracket until the pin(s) drop into the valley(s) 65 ofthe sawtooth pattern 61, thereby providing another form of detentengagement of the bracket 30 f to the component 20 f. The component maybe disengaged from the detents either by pulling on it with sufficientforce to cause the pin(s) 62 to ride up the sloped sides 66 of thevalleys 65 or by lifting the component 20 f slightly so that the pins 62rise out of the valleys 65, and then pulling the component 20 f out.

While the invention has been described in connection with an exemplaryrack system in which access to the rack is afforded from the front ofthe rack, it should be understood that this scenario is merely exemplaryand that the principles described herein can also be applied insituations where the rack is accessed from the rear and the component isslid into the rack from the rear. In such cases, the bracket may beattached to the front of the rack through a slot opening in the rear ofthe rack with the arm extending from the front of the rack toward therear of the rack, and the component is slid onto the bracket from therear of the rack. The rack is accessed from the rear and the componentis slid into the rack from the rear. Likewise, the principles describedherein can also be applied in situations where the rack is accessed froma side of the rack and the component is slid into the rack sideways. Insuch cases, the bracket may be attached to the far side of the rackthrough a slot opening in the near side of the rack with the armextending laterally from the far side of the rack toward the near sideof the rack, and the component is slid onto the bracket sideways fromthe near side of the rack to the far side of the rack.
